Legendary dance music producer Frankie Knuckles died today unexpectedly. Famous for pioneering house music in Chicago in the 1980s, the Bronx-born producer was just 59.
His machine-driven electronic dance sounds shaped an entire generation of musicians, and tributes have been pouring in from stars across the UK, and worldwide. Christened the "godfather of House Music", he worked with and remixed the songs of artists such as Michael Jackson, Luther Vandross, Toni Braxton and Lisa Standfield.
Video report from ITV News Correspondent Richard Pallot.
Last weekend Knuckles, whose hits include Your Love and The Whistle Song, DJ'd at the Ministry of Sound in London.
No cause of death has been revealed, but several music sites are reporting that he died of complications from Type 2 diabetes.
His friend and business partner David Morales announced the news on Twitter.
I am devastated to write that my dear friend Frankie Knuckles has passed away today. Can't write anymore than this at the moment. I'm sorry.
DJ Judge Jules told ITV News it was not an exaggeration to say "just about all dance music today" bears a Frankie Knuckles influence.
The Pet Shop Boys described him as a "true dance legend and pioneer" whilst Pete Tong said he was a "gentleman genius groundbreaker".
